SPECIFICATION forming part of Letters Patent No. 785,578, dated March21, 1905.

Application led January l2, 1905. 'Serial No. 240,822.

To all wif/0m. t may concern.:

Beit known that I, FRANK MCM. VSAwYuR, a citizen of1 the United States,residing at Charlotte, in the county ofl Mecklenburg and State of NorthCarolinahave invented certain new and useful Improvements in Molds; andI do declare the following to be a f'ull, clear, and eX- act descriptionof' the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.

My invention is an improved mold for molding roofing-tiles and otherlike articles; and it consists in the construction and arrangement ofdevices hereinafter described and claimed.

The object of my invention is to provide an improved mold of thischaracter which is adapted f'or molding a number of' tiles simul#taneously and the parts of which are adapted to be readily assembled andseparated.

In the accompanying drawings, Figure 1 is a perspective view of' a moldembodying my improvements. Fig. 2 is a detail top plan view of' thesame. Fig. 8 is a detail perspective view of' one of' the separablemold-pieces, and Figs. 4, 5, and 6 are top plan views showingmodifications in the construction of the inold-pieces.

In the embodiment of my invention I provide a suitable number of'transverse moldpieces 1, which are preferably made of' sheet metal, butmay be made of' any other suitable material and are of' any suitablef'orm.

In the form shown in Figs. 1 and 2 each transverse mold-piece is curvedor arc-shaped and is provided at its vertical sides with flanges 2,which form side walls and which are approximately at right angles to thecurved portion of' the mold and lie in converging planes, so that when aplurality of the transverse mold-pieces are assembled and placed side byside, as shown in Figs. l and 2, the side flanges or walls 2 oil onemold-piece bear against the curved portion of' the next adjacentmoldpiece,so that mold-cavities are formed between the said mold-pieces,into which any suitable plastic material-such as a composition of'cement, sand, and water, which may be colored to any shade desired bymeans of a suitable pigment incorporated in the compositionmay be placedwhile the composition is in a semitluid state, the composition when setforming tiles or other articles which will be of' a size and shapedetermined by the size and shape of' the mold-pieces.

Within the scope ofl my invention any suitable means may be employed forholding the mold-pieces together when they are thus assembled, and anysuitable number of' moldpieces may be thus assembled, according to thenumber of' tiles or other articles that it may be desired to moldsimultaneously.

For the purposes of this specification I show clamps 3, made ofyoke-bars tand tie-rods 5, which connect the yoke-bars together and havescrew-threaded engagement therewith, the saidiclamps being employed f'orholding the mold-pieces together. It will be understood that the sidesof the tiles will be formed by the side flanges or walls 2 of themold-pieces and that the tiles may be readily removed from themold-pieces when the latter are separated after the composition has set.

In order to form the nail-holes in the tiles to enable the latter to besecured on a roof, each of the said mold-pieces is provided at asuitable distance from its upper end with an opening' 6. A rod 7 isplaced in the said openings after the mold-pieces have been assembledprior to placing the composition in the mold-cavity, and the said rod iswithdrawn from the said opening after the composition has set and servesto leave the nail-holes in the molded article.

Within the scope of my invention the side flanges or walls of' themold-pieces may be of' any suitable construction. In Fig. 4 I show amodified construction of' mold pieces in 'which each mold-piece isdoubled and bent restruction of` mold-piece, in which the sidev flangesor walls 10 are soldered to the moldpiece.

In Fig. 6 I show another modified construction of the mold-pieces, inwhich each mold is formed at its opposite sides with integral re- IOOIov

versely-bent side walls 1l l2, and the said mold-pieces are bent in theform of compound Curves and are adapted to produce S-shaped orcompound-curved tiles, as will be understood. Other modifications may bemade within the scope of my invention, and I do not desire to limitmyself in this particular.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of my inventionwill be readily understood without requiring a more extendedexplanation.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. A mold of the class described comprising a plurality of separabletransverse mold-pieces formed with side walls or flanges, said sidewalls or flanges of each mold-piece bearing against the next adjacentmold-piece, whereby F. MGM. SAVVYER.
